These are carry-all-the-time tweezers -- they're tiny and they slide into a guard that keeps them flat. Also known as "Uncle Bill's Tweezers," they are carried by some US military personnel on dog-tags, but you'll probably keep them on your keyring or attached to a Swiss Army Knife or Leatherman. The tweezers were designed to be extremely precise -- they come to a precisely matching pair of points which make it easy to select even very small items and apply concentrated force. -- they come to a precisely matching pair of points which make it easy to select even very small items and apply concentrated force. Their springiness provides a push-back force which makes them easy to operate. I've been carrying them around with me for two years now and have pulled a couple splinters out of myself and one from my girlfriend. Each one was much easier than with conventional tweezers, even full-size tweezers. There's no sign of their losing their precise alignment or the springiness that makes them easy to operate.
